Alternative divertor detachment studies extended to ELMy H-mode on TCV H-mode power threshold on TCV weakly dependent on geometry for Standard, X-, Super-X, and Snowflake Partial detachment achieved using N2 seeding ELMy H-mode detachment extended to X-, and Super-X Movement of impurity radiation front 20% slower in Super-X case Stronger drop in target jsat for X-Divertor As in L-mode, radiation in outer leg increases by ≈50% in X-Divertor, but absolute level is low Extend studies next to higher Psol and baffled configurations [1] C.
